Thanks for your input. I know the situation I am in is absolutely not the norm. I have an older brother, happily married, his wife is like an older sister to me and trust me I know how a marriage is supposed to be. There is no one size fits all in a marriage, but I do know this status quo that I am in isnt right. There is the element of attachment and love here, I do love her but its fading away.
For example, last night I told her how I am planning on taking my parents, specifically moreso my mom on a spiritual pilgrimage since I dont know if my mom will be alive next year. She threw a tantrum in how I dont prioritize the marriage yet I have been there numerous of times, all of which have gone to s***. She insists and expects my older sibling take them as opposed to me. While "missing me" is one idea to this is what she claims, if thats the case, then Id imagine she should help close the gap and do the immigration paperwork properly. But she doesnt, why? For a CR1 a medical evaluation is needed and information must be disclosed, which she doesnt want to do, so she picks these random BS fights to keep stringing along.
But I honestly am glad I wrote about this on this forum. I came for immigration advice and I got a lot more than I asked for in good ways. I appreciate your insight.
